How is an isosceles trapezoid related to an isoceles triangle?
If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.
How many symmetry line does an isosceles triangle have?
One - from the vertex between the sides of equal length to the centre of the opposite side.
The equal angles of an isosceles triangle?
To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.
Can an obstuse triangle also be isosceles?
No, an obtuse triangle cannot be isosceles. An isosceles triangle has two sides that are equal in length, but in an obtuse triangle, the angles are all greater than 90 degrees. Therefore, the sides cannot be equal in length.
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
Does the angle bisector of the vertex angle of an isosceles triangle divides the triangle into two congruent?
Only if the vertex angle being bisected is between the sides of equal length will the result be two congruent triangles.

What is the measure of the vertex angle of an isosceles triangle with base angles measuring 30 degree?
120 degrees.
What is the angle of an isosceles triangle?
The two angles that are not the isosceles vertex are equal.
Does isosceles triangle have a vertex angle?
yes they do
How does an isosceles trapezoid look?
Base angles are equal and sides are equal in length. It looks like a isosceles triangle that has had its vertex cut off parallel to its base.

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
What is the maximum vertex angle in an isosceles triangle?
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
